HEATING', COOLING, AND VENTILATING, SYSTEM,

i Specification of Letters Patent.

Application led March 5, 1910, Serial No. 547,554,

To. all whom t may concern:

Be it known that I, FRANK- P. Mins, a citizen of the United States, residing at Chis cago, in the county of Cook and State of Illinois, have invented certainnewand useful Improvements in Heating, Cooling, and Ventilating Systems, off which the following is a specification.. My invention relates to improvements in heatlng, cooling, and ventil'ating systems, and has for one of its objects to provide a simple, compact, portable, self-contained device, by the operationof which air may be taken into an apartment, cleaned, heated or cooled, and by the operation of which all of the foul airmay, at the same time, be removed from the apartment.

Another object of my invention is to provide a device of the character described whereby the air forced into the room may be medicated, or pregnatedwith a suitable volatile or other sterilizing substance for the purpose of perfuming the air, to destroy germs therein,I and rendering more sanitary the air which the occupants of the apartment are to breathe.

Other and further objects of my invention will become apparent to persons skilled in the. art from the description and the accompanying' drawing, wherein* Figure 1 is a central longitudinal section of the device in elevation; and Fige 2 is a cross section taken on line 2-2 of Fig. 1.

In each of the views the same reference characters indicate similar parts.-

5 is a casingdivided into three parts comprising a central chamber, 6, in'which is lo- -cated an electric motor, or other motor, for

imparting power to the fans, located in fan chambers, 7 and 8, respectively. The motor, 9, is provided with shaft, 10, upon the end of which are secured the fans, 11l and 12, in chambers, 7 and 8, respectively. The chamber 8l communicates with the interior of the room by means of an intake pipe, 13, which may extend to the lower portion of i the apartment or room orto any height desired for the purpose of removing the foul air from such chamber or apartment.

-f In Fig. L L have show-n the. discharge outlet, 14, at the top of the. casing, but it is ap- `.parent that it may.w bev at either side and conveniently arranged: fordischarge of' air into the outside atmosphere. rlhe casing, as a whole, is mounted upon a sideboard, 15, vwhich is adapted to, be included in a window casing'in association with the window sash, .16.. An opening, 17, is made in the board, l15, and this-opening communicates with a downwardly deflected conduit or opening, 18, in the central chamber, 6. The air from ,the exterior enters theA opening, 17, passes through the. conduit, 18, thence downwardly into chamber, 19. Thechamber 19 is a water' 'reservoir or tank extending vthe full length of the device, and adapted to be partially filled. Mounted" on legs, 20-20, is an air-filtering tubing, 21. The tube, 21, is composed of wire. mesh fabric, 22, surrounded' with a relatively fine mesh cloth lfabric, 28. Apart of the cloth surrounding the wire mesh tube may dip into the water reservoir, 19, *below the surface of the water, 24, therein, as at 25, so asmto maintain the cloth fabric` 23 damp by the capillary effect of that 'part of the cloth which is in contact with the water.

When the air enters the` chamber, 19, from -the opening, 17, andf conduit, 18, being drawn therein by the operation of fan 11, it is brought intoV contact with the damp vapors within the chamber- 19, and any 'sub1v stances as dust, germs,-etc.-, therein are precipitated and deposited inthe water 24, A pipe 25, communicates with the tube, 21,' and is connected to the eye `of the fan 11. The suction produced by the fan causes the air to enter' the foraminous tube 21, through the wire and- 'cloth meshes, which are more or less damp, and in passing therein and in contact therewith becomes humidified to a greater or less extent and at the same time Patented July 25 1911.

the substances 'carriedl in suspension in the air are deposited on the exterior surface of the tube 21.

A chamber, 26, is provided, through which the tube 25 passes in joining the tubes 21 vand fan 11. The chamber 26 may be filled with ice, 27, or hot water, as the case may be. If it is desired to cool the air before it enters the apartment, the chamber 26 lis filled with ice, so that the air, in passing through the tube, 25, comes in contact with its chilled walls and becomes cooled before entering the apartment. If it is desired to heat the air, the chamber is to be lled with hot water or other heating agent.

After the air passes into the tube, 25, it is drawn into the casing, 7 and is discharged into the room or apartment through the opening 28.

A damper, 29, is provided for the opening, 18, by means of which the quantity of air admitted through said opening may be regulated, or the o ening 18 may be entirely closed thereby. Another opening, 30, is provided on the opposite side of the casing, 6, and this opening is provided with a similar damper, 31. If the damper 29 be closed and the damper 3l be opened, the air will be taken from the room instead of from the exterior thereof, by the operation of the device, and it will be humiditied, cleaned, and heated or cooled, and returned to the' room in a more sanitary comfortable condition.

At the bottom of the casing is asmall dependingtube, 32, in the lower end of which is a valve, 33, supported by a float, 34, normally vresting upon the upper surface of the water,

24, within the casing 19. A tube, 35, open longitudinally through its bottom wall, is supported immediately above the porous tube 21, and is provided with a wick, 36, which extends longitudinally of the tube, 35, and projects through the opening therein into the interior thereof. The tube, 35, is connectedwith the tube 32. The object of the tube 35 and wick 36 is to moisten the up- Y per surface of the tube 21.

When thc water`24 is lower in the casing or tank 19 than the height at which it is to be normally sustained, the float 34 will descend in response to the lowering of the upper surface of the water, and cause the valve 33 to open the communication between .the

p tubes 32 and 35, and permit the entrained water from the ice chamber, 36, to pass into the tube 35. The wick 36 provides a means -for distributing the Wat-er evenly and uniformly along the top surfaceof the tube 21.

The chamber 37, which is designed to contain the medicated or similar substance which may be in the liquid or powdered form, is connected to the tube, 35, by means of a tube or pipe 38. Any means for varying the flow ofthe medicinal material to the tube 35 may be provided.`

From the arrangement of the apparatus, it will be observed that the quantity of air removed from the room .is substantially proportional to the quantity of air taken into theroom, and for this reason the pressure of the air in the room or apartment may be maintained uniform.

Having thus described my invention, what I claim is:

In a device of the character described, a casing containing a fan chamber, and a motor chamber, and a separate water chamber, the latter provided with an air intake, arranged to direct the incoming air directly upon the surface of the water 1n said water chamber, and an elongated conduit made of reticulated water holding material, and otherwise closed, supported above the water level in said water chamber, and an imperforate conduit connecting said perforate conduit with the intake openin of said fan casing whereby the incoming air is cleansed and humidiiied. v
